Answer 82Answer :AExplanation:A chaincode package that was signed at creation can be handed over to other owners forinspection and signing.

You want the realcost of sending a transaction to always be the same, so you can"™t really expect Gas to beissued, currencies in general are volatile. So instead, we issue ether whose value is supposedto vary, but also implement a Gas Price in terms of Ether. If the price of ether goes up, theGas Price in terms of ether should go down to keep the real cost of Gas the same.Answer 87Answer :A
